I am seriously getting the Stingray Itch. A LFS has some small one. Some are about 5 inches and another tank are about 7. Mainly Motoro. I have a 75 with just a couple of things in there. I may start off with one of the 7 inchers in there. I need to yank the gravel and add some sand first....
Eventually I would be looking at something large, square and relatively shallow for Rays. How fast do they grow? I can't house one in a 75 forever....
